Patent number: 11701939Abstract: In a method for determining an axle load on a mechanically and/or pneumatically/hydraulically suspended vehicle, the axle load is determined with the aid of control and sensor means that are installed in the vehicle and/or functionally enhanced. Functions for axle load determination at mechanically suspended vehicle axles (4) and for axle load determination at pneumatically/hydraulically suspended vehicle axles (2) are available. In a mechanically suspended vehicle axle (4) a distance measuring unit (9), and in a pneumatically/hydraulically suspended vehicle axle (2) a pressure measuring unit (7) are used to determine the axle load. An initial plausibility check is implemented in an electronic control unit (10) of the level control system (1), on the basis of which the level control system (1) identifies the particular suspension type, mechanical or pneumatic/hydraulic, of a vehicle axle (2, 4) and, thereafter, the appropriate function for axle load determination is activated.Type: GrantFiled: September 19, 2018Date of Patent: July 18, 2023Assignee: ZF CV Systems Europe BVInventors: Ingo Jovers, Johann Lucas

Patent number: 10727624Abstract: A strain relief arrangement (4) for a connecting cable (2) has a threaded pin (12), clamping tongues (13), a union nut (3), an enlarged diameter (10, 11) on the threaded pin (12), an extension (15), and a passage bore (25) for the connecting cable (2). By screwing of the union nut (3) onto the threaded pin (12), the clamping tongues (13) move inward and press against the connecting cable (2) for strain relief. The extension (15) is non-round, and an opening (6) of a carrier element (5) is complementary (7, 8) to the extension (15). An enlarged region (16) of the extension (15) has a circumferential groove (20) adjacent to the enlarged diameter (10, 11). The extension (15) can be introduced into the opening (6) of the carrier element (5) and can be fastened by rotation in the opening (6).Type: GrantFiled: February 7, 2018Date of Patent: July 28, 2020Assignee: WABCO Europe BVBAInventors: Thomas Stellmacher, Ingo Brinkmeier, Ingo Jovers, Johann Lucas
